Send Accounting Request but not expect an response
by Wiegand, Nils 26 Oct '20

26 Oct '20

Hello everybody I am currently trying to get the FreeRadius to send accounting messages (accounting request) but not expecting a response (accounting response). My previous attempts to adjust the policy accordingly have unfortunately failed. Currently I have adjusted the config so that the accounting message is written locally in a log and replied to a second accounting server in parallel via the detail reader. Since there is no Radius service running there, there will be no response. Unfortunately, FreeRadius then first declares this server as a zombie and then as dead. I would appreciate your feedback or help in this regard. I've appended the output from radiusd -X. radiusd –X: FreeRADIUS Version 3.0.21 Copyright (C) 1999-2019 The FreeRADIUS server project and contributors There is NO warranty; not even for

change username/password takes no effect for 802.1x wifi clients
by X Xiao 25 Oct '20

25 Oct '20

I'm running a freeradius to authorize user access on wifi network(EAP). everything works well, I input my username and password I can then login via 802.1x then surf. However if I change the username/password in mods-config/files/authorize, then restart radiusd, I can still surf the internet using the old username/password, no relogin required, until I logoff the wifi network, and relogin again, now I need supply the new username/password. How to force a re-login(via 802.1x) whenever I change username/password in freeradius? Is there a way to do it on freeradius side, or I just restart wifi network whenever I restart radiusd? Thanks,

timeout limits
by Sam T 24 Oct '20

24 Oct '20

Hi all, I did some searching but could not find an answer. in short, we have some users that are getting idle-timeout after under 1 min, but mostly between 20min-5 hours. I have tried moving our idle-timeout from 1500min to 15000min, and also tried 0 Still getting idle-timeouts Is 15000 possibly too long and not recognized by freeradius? does 0 really mean unlimited? My goal is to have no idle timeout or session timeout, or understand how to set these variables to simulate a best practice for no timeouts / monthly timeouts. The device is a windows computer, so it is likely generating a good amount of background traffic via dhcp, netbios, etc (is there maybe a minimal bytle quota that defines idle? or is idle really 0 bytes?) My apologies for not including any logs in this post. I would like to understand the limits of this field, and then gather logs. Thank you for your time!

DHCP server multiple gateways
by Ulisses Buonanni 23 Oct '20

23 Oct '20

Hello. First time using this list :) Need to know if it is possible and then I will appreciate some tips/howto guides. Summary: How to configure (if it is possible) raspberry pi as freeradius server with dhcp (conditional IP range based on username) Scenario: In my shared farm we have 5 houses accessing internet through 5x LTE/4g antennas (each house has its own mobile plan and antenna, but they share local network infrastructure to access the antennas). Network: all devices are in the same LAN: 10.0.0.0 mask:255.255.240.0 Each house has its own access point House1AP - IP 10.0.2.1 - offering IPs:10.0.2.2-10.0.2.100 Gateway: 10.0.0.2 House2AP - IP 10.0.4.1 - offering IPs:10.0.4.2-10.0.4.100 Gateway: 10.0.0.4 House3AP - IP 10.0.6.1 - offering IPs:10.0.6.2-10.0.6.100 Gateway: 10.0.0.6 House4AP - IP 10.0.8.1 - offering IPs:10.0.8.2-10.0.8.100 Gateway: 10.0.0.8 House5AP - IP 10.0.10.1 - offering IPs:10.0.10.2-10.0.10.100 Gateway: 10.0.0.10 All access points are wired connected to a managed switch (IP: 10.0.1.2) This switch is connected through a fiber channel to another switch (10.0.1.1) that is wired connected to all LTE/4g routers/gateways. Raspberry pi (IP 10.0.1.4) is wired connect to the managed switch. Until now every house has its own unique ssid (wpa2 personal) and devices from one house cant access APs from other houses. I'm wondering if it is possible to change all APs to use wpa2 enterprise in a way that freeradius (based on the username -not the mac address ) set IP range and gateway that user belong. For example, if I belong to house1 (using gateway 10.0.0.2) when I go to visit house2 the House2AP should recognize me as house1 and send me the same gateway as house1. Thanks in advance Ulisses

rlm_perl - unresponsive child threads
by P. R.M. 21 Oct '20

21 Oct '20

I'm trying to debug some issues when using rlm_perl with a mysql backend. My module script uses the Perl DBI module in order to access the back-end, and I'm calling stored procedures for each of the radius sections (authorize, authenticate, accounting, etc.). Some of the queries will occasionally take too long (~20-30sec+), and this will apparently cause the freeradius child threads to hang & die (correct?). When this happens, I'll find multiple sequences of entries in the radiusd log file such as the following: Sat Oct 17 21:30:07 2020 : Error: Received conflicting packet from client 0.0.0.0/0 port 55526 - ID: 43 due to unfinished request in module perl. Giving up on old request. Sat Oct 17 21:30:12 2020 : Error: Received conflicting packet from client 0.0.0.0/0 port 55526 - ID: 43 due to unfinished request in module perl. Giving up on old request. Sat Oct 17 21:30:42 2020 : Error: Received conflicting packet from client 0.0.0.0/0 port 40463 - ID: 44 due to unfinished request in module perl. Giving up on old request.

So, I'm trying to figure out how to gain more insight on this problem and hopefully prevent it and/or handle it better. So, my question(s): 1) what specifically causes the child thread to be detached/abandoned? is it a timeout issue within freeradius? - In a normal Perl script that accesses a DB using DBI, a slow DB query will simply cause the script to wait indefinitely until the query finishes (unless a connection timeout occurs), but it wouldn't necessarily die/crash completely. This leads me to assume that there's some kind of hard-coded timeout within freeradius that expires & causes it to give up on the child thread if it's still stuck waiting for a query to finish. Is this correct or incorrect? 2) if there *is* some kind of built-in timeout within freeradius for processing sections via rlm_perl, what is its value? can it be changed/extended via some configuration setting? (I looked around a bit in the source code, but didn't see anything) 3) Aside from trying to guarantee that a query will never run slowly (not realistic in my case), is there anything else that can be done to handle a slow response from rlm_perl, instead of just giving up on the child thread? Some kind of debug logging for cases where the child thread(s) hang or don't respond in a timely fashion?

Credentials differ when proxying
by Julien COCHENNEC 21 Oct '20

21 Oct '20

Hi, I have a server A proxying requests to server B (having LDAP enabled), and a client C requesting A. When I try to connect from A to B with radclient it works. Logs say : Login OK: [blabla2] (from client rad1-eee port 0) When I try to connect from C to A : Login incorrect (ldap: Bind credentials incorrect: Invalid credentials): [blabla2/?Q?#%?????)[~???dW???ŝ7?g-m?[˵] (from client rad1-eee port 0) I don't get why the credentials differ while proxying, which conf file should I check to understand this? Is this part coming from an ldap conf problem or from radiusd.conf problem? /?Q?#%?????)[~???dW???ŝ7?g-m? Thanks for your help. Here's the site-available/default file content : server default { listen { type = auth ipaddr = * port = 0 limit { max_connections = 16384 lifetime = 0 idle_timeout = 30 } } listen { ipaddr = * port = 0 type = acct limit { } } authorize { filter_username preprocess chap mschap digest suffix eap { ok = return } files -sql expiration logintime pap } authenticate { Auth-Type PAP { pap } Auth-Type CHAP { chap } Auth-Type MS-CHAP { mschap } mschap digest eap } preacct { preprocess acct_unique suffix files } accounting { -sql exec attr_filter.accounting_response } session { } post-auth { update { &reply: += &session-state: } remove_reply_message_if_eap Post-Auth-Type REJECT { -sql attr_filter.access_reject eap remove_reply_message_if_eap } Post-Auth-Type Challenge { } } pre-proxy { } post-proxy { eap } }

proxy issue
by adrian.p.smith＠bt.com 19 Oct '20

19 Oct '20

We are facing a strange issue. Using FreeRadius (3.0.15) to proxy some traffic and under certain circumstances the Access-Accept from the remote server appears to be ignored and we see the log message from this code in process.c. /* * No reply, BUT the current packet fails verification: * ignore it. This does the MD5 calculations in the * server core, but I guess we can fix that later. */ if (!request->proxy_reply && (rad_verify(packet, request->proxy, request->home_server->secret) != 0)) { DEBUG("Ignoring spoofed proxy reply. Signature is invalid"); return 0; } If we use radclient to send the same packet direct to the remote server, the reply is received with no issues. We have tried upgrading to 3.0.21 but the same code seems to be invoked. The comment in the code is a little cryptic and I'm wondering if anyone can shed any light on what might be causing this? Thanks in advance. Adrian

cross compiling freeradius

Hello I am trying to cross compile freeradius-server-3.0.21. Until recently we used a 2.x series but upgrading to openssl 1.1.1 forced us to upgrade freeradius too (it is probably reasonable anyway). Now with freeradius 3.0.21 I am running into an impasse as configuration barfs at me: checking for __builtin_choose_expr support in compiler... configure: error: in `/home/mega/leaf/devel/master-new-openssl/source/x86_64-unknown-linux-uclibc/radius/freeradius-server-3.0.21': configure: error: cannot run test program while cross compiling configure reads Configured with: /home/mega/leaf/devel/master-new-openssl/source/x86_64-unknown-linux-uclibc/toolchain/gcc-8.4.0/configure --target=x86_64-unknown-linux-uclibc --with-sysroot=/home/mega/leaf/devel/master-new-openssl/staging/x86_64-unknown-linux-uclibc --includedir=/home/mega/leaf/devel/master-new-openssl/staging/x86_64-unknown-linux-uclibc/usr/include --prefix=/home/mega/leaf/devel/master-new-openssl/toolchain/x86_64-unknown-linux-uclibc --enable-shared --with-gnu-ld --with-gnu-as --disable-libmudflap --disable-libssp --disable-libmpx --disable-libquadmath --disable-libgomp --disable-multilib --enable-languages=c++ It appears that I have to disable parallel testing of the capabilities.

IP allocation from Pool

hi, With the help of below documentation, I am able to allocated the static IP to user from my MySQL DB but is it possible to allocated IP from pool . If yes, can you share me the step how can we manage it. https://wiki.freeradius.org/guide/dhcp-for-static-ip-allocation#let-s-start… guide/dhcp for static ip allocation<https://wiki.freeradius.org/guide/dhcp-for-static-ip-allocation#let-s-start…> Before You Start. This example assumes that the network adapter where is connected freeradius have the following settings: auto eth1 iface eth1 inet static address 192.168.10.1 netmask 255.255.255.0 network 192.168.10.0 broadcast 192.168.10.255 wiki.freeradius.org Thanks, Kabin
